Age has nothing to do with playing strength in chess. There are many children below 15 with IM / GM title. You should try to improve and people play with you. Your current rating indicates that you make too many mistakes. Just pay nore attention to game on hand and your rating will go upto 1300-1400 without any proper training. Any one of age 10 can do that easily. With training much more progress possible.
Any people want to play younger than 15.
