I learned that if you're planning and looking on what kind of business to start in, then don't look outside and be hard on yourself, but look inside. What I mean by this is don't imitate what others are doing just because that business is in or is doing well because chances are it will not work to you or you lose interest on it as time goes by. Look at your skill sets and choose one among those that you really love doing and profitable. Meaning even if you're not being paid to do it, you wake up every day and do it anyway. You will not treat it as a work or job because you love what you are doing. But I warn you that you should treat it as a business. Be serious in achieving your goals at the same time enjoy every moment.
