I see you have JMDP in your avatar so that's a great person to follow the steps of. Looks like you have something done about your tennis career already, just had a break from it. 20 years is an okay age to start playing in futures events for a person with some experience, like you say you have. Remember that some other Agustin (Calleri) was forced to have a break due to financial situation, before started real competition and became so successful. Alexander Waske from Germany started his professional career at the age of 24 y.o. and until now plays challengers and ATP.
Everything is in your hands - good luck. Would you like to share in which tournaments you played so far?
