Always, follow your passion
If you do something without passion, it will be bland, tasteless and very "ordinary"
That was the opening statement I gave to a bunch of fresh meat for the grinder (aka new Employees), as I try to communicate something that has been bothering me for years. People doing the "job" lifelessly. With absolutely no commitment or passion. Just a "job", to "pay the bills" and "get you out of the house in the morning"
Truth is, this is not just for people looking for jobs, just take this concept and graft it to anything you can imagine in your life. Have passion in what you study, not just to get a degree or to get married with it. But because YOU LOVE what you're learning. (If you're not "loving it" then really, don't do it!)
When you talk to people who studied Engineering. Or Physics and ask them, "Why have you decided to study X" their answer would be "Because Y wasn't available" then. You have a classical case of people doing something lifelessly. With absolutely no passion. No conviction and absolutely no aspirations, sans, maybe ... maybe .. making a buck at something they don't like or even care about!
Honestly, we can't all work at the jobs that we like. But we should at least have a plan to get to that job that we want. Even if the current job is just a step in that direction. We can definitely excel at it more than we would at a better paying job that we hate!
Although, my friends would say, "give me the money first, and I'll worry about liking the job" or "I'll like the job, if it gives me the money that makes me love it" in other words, just a form of noble-prostitution. But hey, it pays the bills!
Truth is, people who really love what they do, end up innovating in that field and improving it. Breaking new feat and causing paradigm shifts in how people look at these careers that they pick for themselves
These might not pay well. These might not even be able to support a person, then perhaps it should be practiced on the side, or as a hobby. But, don't let go of your passion.
I would understand it if people weren't able to get the job they want. But what I can't understand is people not following their dream and passion studying the subject they are most passionate about. In this day and age, there is no more "My father wanted me to be a doctor", there is no more "I wouldn't be able to make a living as an Artists" or "Who would pay for my music". Fact is, THE WORLD IS FILLED WITH ENGINEERS, DOCTORS, COMPUTER and IT FOLKS and we REALLY NEED EVERYTHING ELSE! WE NEED other fields to be pursued. Literature, Arts, other sciences are begging for people
So follow your passion, wherever it might lead you. You might regret not making enough money. But you will never regret not following your "true calling" and have the "What if" tape played in your head every single day of your life!
PS, it's NEVER too late!
