There are always going to be people in your life who will tell you what certain things mean: what it means to be successful. What it means to be happy.
Feel free to listen to them and their definitions.
And then, if you want, feel free to disregard them.
The truest thing I know is this: how you define success is a highly personal thing. Some people are motivated by money. If your bank account makes you feel secure, successful, and proud? I am happy for you if you are happy.
See what I did there, by the way? I didn't suggest that someone who is financially motivated is wrong or ridiculous or in need of redefining the rules that he uses to guide the choices he makes. I'm not suggesting such a thing for a simple reason -- I don't live his life. The ways he defines success for himself do not belong to me because, in fact, there are many ways by which one can define success. The important thing, I think, is to make sure that you own your definition, and that you not let anyone talk you out of chasing what inspires you.
I won't be told what it means for my life to have success and meaning.
I'm through being instructed as to what I need in order to be happy.
What works for me -- what makes me feel successful, what I need in order to be happy -- will likely not look like someone else's definition. That's okay. That's actually great. If we all wanted and needed exactly the same thing, the world would be a very dull place indeed. Fortunately for us all, there are people who want to serve in missions and there are people who want to write blogs and there are people who want to be corporate masterminds. There are people who want large, fancy homes and there are people who want very simple ones. There is room for everyone here. There is room for all different kinds of success and happiness.
Mine might not look like what you think it should look like because it doesn't match yours, but that doesn't make it less real or valid.
Look around you. See the people in your life -- really see them. Know that their happiness and success for what it is: personal. Beautiful.
And rejoice in it the way you would want them to rejoice in yours.
