Which is more important?

[anagogy]

What is more important, Love or Wisdom while here on Earth?

Aren't we here to learn compassion for one another?

How can we best do what's most important to do?

I don't want to have any regrets after I die. If I can avoid that.

It depends on the soul. Not everybody is in the same place. You can learn the lessons of any density in any density (in my opinion), just as you can learn the lessons of any grade in any grade (in school) though it could prove very difficult. In every density you face the seven rays. But this environment, or school if you will (3rd density), is particularly calibrated toward learning the lessons of yellow ray, which is where social unity is sought in some manner or another. So for positive, that would be the lessons of love, but for negative, that social unity is sought by conquering and enslaving your enemies (preferably through their own choosing to give up their own freedoms/rights as individuals). So this is love of self, disproportionately weighted towards the self rather than others selves. The graduation into the next density for 3rd density beings is about uniting the social structure (the budding conscious social memory complex) in some manner or another. Integration of this thought-form into a coherent direct-able whole.

However, many wanderers have already went through the love course, and perhaps they are here studying/teaching other things. Perhaps teaching other, more adept lessons. Wanderers incarnate in lower densities for a variety of different reasons. It doesn't always boil down to just one thing that is important. Sometimes beings are literally just on vacation (weird place for vacation amirite?). But then some people vacation in Alaska, and some people go on tropical cruises so different strokes for different folks.

So I don't think you can really boil it down and say one is more important than the other. It is completely unique to the soul. It depends where you are. Turn your will towards the creator and ask for guidance that facilitate your learning regularly, and if you are sincere, you will guided where you need to go.  

I also don't want to let people walk all over me.

It is important to treat others with love, respect, and kindness, but also yourself. That means you shouldn't let someone walk all over you. Show people in your life respect and kindness, but don't just allow people to treat you unfairly. All that does is reward the subjugation. Even the confederation engages in self defense, even though it is not wholly positive or accepting. Disrespecting your self (by not valuing yourself enough to defend your personal well being) is just as bad as disrespecting another. All selves are valuable and worthy of respect.

Even compassion can be imbalanced -- always remember that. Some people want to bleed it out of you because they don't want to have to tap into their own source, they want to bask in the adulation of others. STS beings ultimately cut themselves off from their own inner love. What is the first separation? The self from the self. You can't offer enough behavior to please these individuals. Because the need is never ending, so if you can't bask in the light of your own sun, you try to get light from others suns. You just enable them to subjugate you more and more. So you see, there is a very critical balance between love and wisdom. Love is great and all, but love imbued with wisdom is even greater. Forgiveness is a wonderful thing, but justice has a place too in this universe.

What is wisdom but the light of truth emanating from unity, and what is love but the feeling that emanates from unity? Love/light and light/love.

It all depends where you are, which is unique for every soul.
