There is no hard fast guidelines. It's entirely up to you.
Some people have experiences a few weeks, others months. It's up to your level of discipline and you ability to focus and concentrate. karma helps also [;)]
4 years and still haven't got out, but lots of exciting and intriguing experiences. Never give up.
