It is well worth noting that a very large number of people on high incomes aren't "rich" - they spend most of it. It is just human nature that if you are getting paid a lot, you will eat out a lot, go out a lot, buy more expensive stuff and generally not worry too much about your money (as you feel pretty secure that you are riding high).
End result => a good lifestyle but not much to show for it at the end of the day.
OK of course you will need to develop a decent source of income if you DO want to get some expensive things but just being careful how you spend your money will put you streets ahead of the average Joe. Just check your mates - I'm sure a few of them spend most of their pay-cheques on entertianing themselves & their friends.
Both my parents are pharmacists, & they did well by developing their own businesses. Pharmacy is about people-skills
(the community likes dealing with them as doctor-alternatives), and business-skills
so that you can see opportunities as they arise and can work them into your overall plan.
You would probably build the most wealth by growing / buying a chain of outlets (but this depends on Govt policy in each country), but I have a good friend who did very well as a consultant pharmacist just working for others (for a very good rate). I even know of some guys who did very sell developing & selling pharmacy software (it wasn't much good but it was all there was, so they cornered the market!). There may be great opportunitites in associated ares such as hospital/medical pharmacy services, etc apart from straight retail. What about e-pharmacy? Has that been done well yet? Study well but also try to learn lots about how the whole pharma-medico sector works (which players are doing what, what sectors are developing, what govt regulations are changing, where are people moving to, where are services most likely to be needed, etc). Getting into a business in a new or fast-growing developing area is the key.
Good luck & keep that Ferrari foremost in your thoughts!
