Of my investments that have been realised, buying my first house turned out to be a pretty good move, which I didn't really realise at the time.

I'm incredibly fortunate and it's important to me to make sure that I give back where I can.

Since there are a wide range of entrepreneurs fundraising at any given time, I looked at each opportunity as it has arisen and on its own merits. Then I've sat down with my financial advisers, we've looked at the numbers and gone for the businesses I believe have real potential.

Prayer is the natural and joyous breathing of the spiritual life by which the heavenly atmosphere is inhaled and then exhaled in prayer.
