Embracing curiosity and exploration can be life-changing; embracing play, lifelong - it's a universal form of lifelong exploration among primates. Also, plenty of research supports exploration's powerful affect on aging minds (though I don't know your age) in many ways. And as a wonderful effect, you find new things that you love. And remember that part of exploration is dead ends and failures - if you aren't failing, you aren't trying.
Also, life changes take a bit of time, like turning a big ship - an accumulation of things need to change. Just beginning to head in that direction - changing the derivative of the derivative of your path, in geek terms - can change your outlook, give you direction and goals; you're embarked on a long journey.
There's no panacea. Life can still feel pointless at times. For me, at least, the trick is to recognize it's my emotions, to have compassion for them - life ain't easy - and to put my head down and just do the things I know are right. And when I come out of it, I feel proud of what I've done and in a better place to move forward. Always do things that leave you a little better off than when you started.
Good luck! I hope that helps!
