I consider financial success to be when I can afford whatever I want to buy without worrying about it. Right now, that is the position I'm at, but I know once I leave university I will cease to be financially secure, as my money I earn from work (£8.90 an hour) won't be able to sustain anything great. But right now, I have everything I need, I can afford anything I want, I have savings, I have a pension, and I'm happy. Ask me in 2 or 3 years and I'll probably be a struggling young professional. Hence why I've already begun saving, so if I hit hard times in the future, I'll hopefully be able to cope a little bit better.
