How To Stop Feeling Uncertain About The Future

What's up guys, in this video I want to discuss with you the problem of feeling uncertain about the future and the fear of the unknown.
My thoughts grew from my strong desire to pursue a psychiatry, before falling into a constant loophole of trying to pin it down as an absolute certainty of a future.
Disclaimer: I have obviously edited out the 'hms' and 'uhs' of the video but I've kept the streams of my thoughts original to keep it as a discussion. I'm not here to 'teach' you anything, just sharing my thoughts as they are.
Leave your thoughts too if your mind is occupied by similar struggles, let's talk about this.
