Is positive psychology counter-productive?

Psychology is a complex yet interesting discipline, giving us some ideas on how our inner universe works. I have always thought psychologists or even psychology majors are one of the most powerful people because they have the tools and skills to analyse what and how we think.

Back to the question. I’m wandering again.

I just realised no one has told me these advices even once:

Following your heart may not be the best option.
Stop pursuing happiness.
Never do things you are good at.
Stoicism (and not optimism) may lead you to a better life.

On face value, these sound rude and ultimately depressing. Are we really killing somebody else’s dream when we recommend stopping the pursuit of happiness? Does doing things one isn’t good at dwarf potentials to excel? Does stoicism cease us from dreaming and foster contentment in mediocrity? Why not follow our hearts when we only live once?

Although unsurprising, I wonder why I never heard these when talking with family, friends, and colleagues. Perhaps we’ve been too aversive of the negative that we play down its value in any possible transformation, or we’re too timid to state the actual and real.

Or, are we that used to a results-oriented society to the point that even happiness becomes merely a goal/state we must achieve?

Regardless, why don’t we bravely take the non-conventional, uncharted approach? Why don’t we violate and question the mainstream for a meaningful tomorrow? Why not choose the yet-to-be-proven over the proven ones? All at the expense of risking the so-called attainment of happiness.

Once again, I’m full of questions and nothing has been answered. At least I ask.
