In the late 1980s I was working as a fund manager in the City and fellow commuters looked as miserable as sin. It made me re-evaluate what I wanted from my life. I decided to move into the third sector and got a job at the Charities Aid Foundation that used my investment skills. I was there for 13 years, eventually becoming director of communications.
I'd tell anyone thinking of working in this sector to go for it - there are emotional and ethical pressures, but it's wonderful to be a part of it. If you progress to running an organisation, it can be easy to get caught up in politics, but I always try to focus on the decent and honourable thing to do. Being honourable is why most of us come into the sector.
When I joined Make-A-Wish 10 years ago, there was only £10,000 in the bank and 350 children waiting for a wish. After four months I had to tell staff that they wouldn't be paid that month. The low points involve people, such as restructuring and telling colleagues they will lose their jobs; but granting wishes to children makes us all proud. I love this place, but now is a good time to leave. The charity's total income and the number of wishes granted have both tripled - this year income is expected to reach about £7.7m and 1,000 wishes - and I feel my successor can take the charity on to greater things.
We deal with such a serious subject, so it's important not to take life too seriously. There hasn't been a day in my career when I haven't laughed or grinned broadly with colleagues.
