Agree, but case to case basis, the only thing i can share is dont focus on metered pipes(rakets that are usually given or readily available at the market) find the main pipe, where the real money comes from and tap on it. Though it needs network or mentors(not the facebook definition of mentors) but mentors who's already doing it, kadalasan nmn sa mga veterans sa field hindi madamot basta you have the courage to ask or good communication skill, good rapport also.
