I've worked in the Finance and Technical industries for most of my adult life. Seeing how quickly everything changes, has always kept me back from risking everything and possibly losing it all. However, as I'm older (32), I've start to realize that there's only one way to live life; and that's positively. It doesn't matter if risk exists. What matters most, is that one believes in one's own self-worth and our own abilities.
Having said that, I still find myself struggling to push myself. However, slowly but surely, success will come.
Now that I know that you're both Nigerian and have an entrepreneurship frame of mind, I'm looking forward to your posts even more!
