I e-mail this one super experienced in engineering, asking about career path for one specific field in petrochemical, and he replied;
If you think it is possible, then it will be possible. All you need is a clear vision and choose the path that you wish to take, then plan your action accordingly with considerations of opportunities, your interest/passion.
I'm feel pump up with such positive comment from him. Hopefully we do our best and after that lets ALLAH decide the best for us. ALLAH's plan is the best
