Any comedians or writers out there that have some good advice?

I have been writing comedy all year long and I plan to do some stand
up. My ideal self would be writing funny scenes for a tv show or
sketch comedy or writing for comedians in my future, for my career.
Any advice on a good place to be or school to attend or class to take
or anything? I feel a little stuck. I didn't know if there was anyone
out there who is a successful comedic writer and knows where to begin
or a good move for a writer like myself..
