1 READ OFTEN. i dont just mean fic. read books, poetry, articles. find beauty in syntax and then break every rule you can as you develop your voice and prose
2 WRITE OFTEN. the more you practice the better you get
3 TALK TO WRITERS. get feedback from other creatives, it helps!!
guys im so serious start to strength train NOW that you are young and capable instead of waiting to be in your 50βs full of long term injuries and illnesses.
If you're an artist keep learning, practicing & creating. A bunch of people who have no clue how anything works will tell you to give up, you suck, you'll be replaced etc. These are societal pressures artists have always faced, learn to build resilience. You'll be alright.
