Don't Feel Guilty About What Motivates You
If you've got something-- run with it.
We tend to judge ourselves too harshly about why we are motivated to do things that better ourselves. One may say we shouldn't be motivated by power, success, money, love, or fame.
Indeed, some motivations are perhaps more noble or virtuous than others. Still, pursuing your goals or callings should be done selflessly and without judgment. Yes, your ego will likely be a variable in your new pursuit (especially if your vision for your life has to do with its self-improvement,) but as long as you’re not hurting yourself or others, it is not up to you to judge that desire for improvement.
Words are often laced with hidden and double meanings. If we think in language, our inner voice speaks these desires within, we then wrestle with the various interpretations, the unlikely what ifs, and criticize what may have motivated such an utterance.
If what motivates you is not harmful and inspires you to action, and you are not attached to that concept, I believe that it should not be judged but harnessed. I believe the universe gives us various symbols, signs, and messages that we can not likely accurately interpret when we first think or feel it. It is our job to act on those symbols for our betterment. Later we will understand those notions, or we will abandon them altogether.
Whatever happens, you’ll be a better person because of it. The fundamental motivation for self-improvement is, in itself, profoundly noble.
