If I could sit down with the 25-year-old version of myself, I'd have quite a few things to tell him...
I'd start with this:
Decide what you want.
Decide quickly.
And once you've decided, stay with it long enough to make something happen.
Stop jumping from one idea to another.
Stop second-guessing yourself.
That doubt you're entertaining?
It's going to cost you more than you realise.
Time. Money. Opportunities. Years.
I'd tell him to start saving and investing immediately.
Not when he starts earning more.
Not when business becomes successful.
Now.
I'd tell him to marry Vivian.
And when he does, to be the kind of husband who leads responsibly, plans with his wife, and builds a life with her rather than simply living from one day to the next.
