I just want to share the right approach for being a businessman: Everything you do always has to be 'win-win,' as much as possible. Enter any venture with the proper tools, the proper capital, the proper preparations, and studies. You can't lock your horns with the stablished businesses. There's too many watches and cellphones today, even designer ones. You can't go into business like that because you end up having to compromise some things, somehow, somewhere. You have to sell the real thing, you don't sell illusions. And you don't get rich by being an employee. Be an enterpreneur. As one, do something different or do the same thing differently. If you offer quality, you can't help but get quality back. Don't be afraid yo go out of your own. You won't get much out of life if you're afraid.
When you're a positive person you attract positive things. Be positive and don't try to cheat people. Eventually, you'll attract a lot of good things, good businesses.
Disappointments come when you bite off more than you chew. You can only do as much. You may have a lot of good ideas bu a concept is only good if you can give it your all. Never let disappointments get you down. Think of the achievements that you have or those that are in store for you in your other ventures. You're still alive, you can always find success elsewhere.
