Making your money last long enough is a lifetime’s work. I did some thinking, and I offer you these major money milestones everyone should observe:

20-30: Learn to invest, and start putting some money into a retirement account.

30-40: Keep planning for retirement. If possible, buy a house. Start saving for your kids’ college.

40-50: While still saving money, spend some of it to enjoy life. Talk to your parents about their finances to avoid unpleasant surprises as they grow older.

50-60: Analyze your retirement plans to make sure you’ll have enough money to retire. Adjust your saving strategy if necessary.

60-70: Start collecting Social Security. Takeadvantage of senior discounts. Put aside some of your savings for long-term medical needs.

70-80: Analyze your spending. Talk to your adult children about your financial situation.
