Well if your just starting soccer with no basic skills it will be hard but not impossible to succeed but if you have even basic skills it's ok. Here's a few tips...
1. If you're just starting soccer train between 15 mn and 1 hour every day to get familiar with the ball (you get training drills and all on line and you'll surely make friends on the pitch(outside your team) who'll be willing to train with you)
2. Every 4 months add a training hour to your maximum football training time, you'll be more confident with the ball and have more fun on the pitch
3. More you get familiar with the ball the more pleasure you'll get out of the game. Before I took pleasure playing soccer now I'm euphoric everytime I touch the ball
4. On school days don't do more than 1hour of soccer to be able to do your homework and prepare your exams
I started Soccer 2 years ago, I was fourteen and on the bench, I got recruited by a senior team after some really good performances and am now going to start my first season in a senior league(12th french division)and can't wait to score loads of goals!:-)
