Itīs tough to become an all-surface-player. There are very few guys who can do that really well.
Look at Andy Murray, when he was teenager was sent to Spain to learn to play on clay, he spent a year there, and now, well, itīs his worst surface so far.
I have played on clay all my life, only played on hard court 2 times, and it really got me crazy, it seems to be a completely different sport
