If we all die doing something that made us happy, and hardly anyone remembers what we did (unless we do something ungodly great to impact the life of future generations) then what should we really be doing? I do what makes me happy and that's playing the bass. Will I get any recognition for it? Probably not. The chance of having your band make it big-time is about the same as winning the grand prize in a lottery.
So you imply doing something worthy of others remembering and getting recognition makes you happy. If so, pursue it and be happy for the opportunity to pursue it. If the pursuit does not make you happy then pursue something that makes you happier. Pursuing a goal that is highly unlikely of being achieved when the pursuit does not make you happy is not worth the effort. Put the effort into something better to achieve happiness.
I'm sure you realize being recognized and remembered is not everyone's path to happiness, although it certainly is for some.
Some are happy to simply raise their kids, others to be a corp CEO, others to live in a forest, others to worship, others to travel, etc...
Become sincerely happy and stay that way over the long run and you'll know the meaning of your life. It will be self evident. If you pursue things that result in unhappiness or less than the fullest potential to be happy then you will likely continue to question the meaning of life.
Everyone must choose their own path towards happiness to achieve the fullest meaning of their life.
