I'll add by saying, that another tips is to ask or seek for the experience of those that have been in the business long before you. Learn from their mistakes and build on them too. For it would really go a long way to helping anyone in his decision making while wanting to invest in any way.
In other words, seeking mentorship from senior colleagues who are doing well is a tip that shouldn't be over looked as it is best learning from the mistakes of others rather than making avoidable mistakes when you can learn from others.
