1) Play the game with someone everyday or every other day. The other person doesn't need to be good but you both need to be trying to beat each other constantly and having fun. Do that until you find a character you enjoy and can beat the other person with. Also until you understand the way the game feels, until you understand the flow, all the characters basic move sets, ect. Play until you love the game, don't go through the next steps if you don't.
2) Search around your community and find people who have been playing the game for a long time and are better than you. Lose to them and ask them for advice. Learn neccesarily tech skill to keep up with them and then come back and do it gain and ask for advice. Then start reading about the game and watching in depth videos of tech and analyzing matches, second by second.
That's how I started and I'm doing pretty okay.
