Though your fears that the same returns will not repeat are definitely not unfounded, I guess the author has clearly mentioned in his article "While one should not expect of such sky-high returns one can at least give her/his best shot". Further, the point he is stressing is not about ways to obtain 134% yearly return on Mutual Funds, but that instead of spending hard earned money on 'short term-joy infusing' ways (like buying teddies, sarees etc), spend it on building an investment. Its clear from his line again "Now this also does not mean that anyone investing in the above will generate similar returns in the future. Definitely not, but what we are talking here is that some gifts when thoughtfully given can be lot more fruitful than others."
