Thank you. I started a coin and stamp business in the early 1970s and started saving some of the profits, I then started an electronics business and closed the stamp and coin business, keeping the stamps of significance and started buying scarce and rare stamps. I eventually closed the electronics business and created a computer repair business which I had for 33 years, in the process buying more scarce and rare stamps. I retired myself due to health issues and now spend time buying scarce and rare stamps from a stamp company specialising in scarce and rare Australian and Commonwealth stamps. I am very specific with the stamps I buy, they must be in perfect condition unless it is impossible to find another (I have a block of 4 and a single stamp that are one-of-a-kind and extremely rare).
