Well, I myself write songs and stuff, and have been into music for a while...
Here's what I suggest:
1) Always keep a notebook with you. Write, scribble, draw - anything that EVER comes to your mind.
2) Get some air everyday - just take an evening walk, alone. And while doing so, just ask yourself, "Who am I? What do I love? What do I want?"
3) Don't take long breaks - you may never have the incentive to play again, or dream as much again. There are days, when I play my guitar for 4-5 hrs, and there are days wherein I just pick t up for 15min. Infact, it'll all the same - just show yourself how much you love music.
4) Whenever you're done with something, record it. Publicize it. And be open to criticizm - don't get swayed by it. It should just motive you to work harder.
5) find someone who cares - first about you, and then about your music... Jam up, talk nonsense, have icecream together, dream together... This helps a LOT
6) and finally, have fun! :-)
if you need any real help, with lyrics and stuff, feel dree to message me!
ps - all ideas never work; only some do. I myself scrap iut about 60% of my attempts. But that is one of the best ways to learn and improve
