There is no definite 1 way about it. But one thing i'm sure of, u certainly hv to invest to make ur money grow. u can try investing in insurance for a start, or even, depositing money which u most probably won't use in the short-run in fixed deposits. if u're more daring, u can try ur hand in stocks. here, it is generally advisable tt u hv a thorough understanding of the market before investing. cuz what might happen theoretically is often not manifested in reality. in reality, the opposite may just happen. u can also target stocks which pay gd dividend rates. however, all these experience requires much time and effort on your part to master. if u're not willing to invest the time to do so, it's better to stay clear of stocks. bear in mind, it is good to take risks. but, u muz ensure tt u are able to bear the consequences should ur risk backfires. so, do not rush blindly into investing ur hard-earned money or u could end up going burst one day.
another quicker way is of course through business. but, unless u hv a unique idea to market, it's unlikey u will make it big in this field. all said, u must also ensure that u do not incur more than u earn. that is, u hv to cultivate e habit to save a portion of ur income and not purchase commodities such as cars that would depreciate in value should there be no neccessity to do so. remember, necessity means whether u really need the product or not, and not because u want it. don't invest in a car just for a mark of status. u can do so later in life when u're financially stable. otherwise, u would be burning holes in ur pockets, where money drains out faster that it arrives.
