"Do what you love" is perhaps the most trite advice there is for new graduates. It's ok advice but it also encourages the entitlement complex of young people! You don't deserve anything just because you love it. You have to work at it harder than you ever thought you would and you'd have to do it for little money in the beginning. Passion, however, does not guarantee success.
Bottomline: you can't be sure about anything and no one owes you jack shit just because you graduated from school. But there is someone out there who has a vested interest in your success - you. You are the only person who can truly make things happen for yourself. Don't expect anyone else to give you any breaks, because they don't have to.
That said, these are three other things I wish I knew when I graduated five years ago.
1. Your first job should be in the field you truly want to be in. Graduates typically consider two jobs: the job they want, and the job that earns them security/ money. (Lucky if you get both!) They think, "I'm gonna take this okay-paying job first and when I've saved enough I'll go on to be a makeup artist!" Everybody's situation is different but if you're are able to pursue something without you and your family starving to death, you better go for it.
Why? Because the longer you stay in a job you dislike the harder it is to leave it. The more time you spend there, the more time you lose in gaining valuable experience and contacts in the industry you want to be in!
If you spend your first two years in a job you don't like then those two years mean zero in a completely different field of work. Of course, it doesn't all have to be a waste. Spend all your free time doing that thing you love so that when you're ready to leave, you have something to show prospective clients.
2. "Pwede na" should never be an option. When you submit your work, it has to be the culmination of your best effort. I suspect that our generation was conditioned to think that cutting corners and spending the least amount of effort on something is admirable. It's not.
