My dream is to reach high mmr and to become representative in esports

Hi, I am ro1 a pos 4/5 player, willing to be a professional player someday. My highest mmr I have reached was immortal (5670) top 4250 in sea, however my current rank for now is 4.9 mmr because I am adjusting to a new rank environment which is pubs. Since Ive played role quoe for a long time. I want to become a pro player because my dream is to become a first sea TI winner someday since I was highschool. However, I dont have any experience about local tournaments in our city. I hope you will help me to better and become pro in dota.
