You should start investing “as soon as you can” so that your investment can grow over a longer period of time.
means you don’t need a lump sum amount to start investing; rather you could start by investing small amounts. It doesn’t matter if these small amounts are only a tiny fraction of your income.
stay away from the herd mentality or what others are doing and make wise choices by investing only in stocks that suit your financial goals. Also, have a sensible investment strategy and make a diversified portfolio with a wide range of assets.
