How to make your life large

I have been thinking this from long time and i have thought that if you want to make your life large than it should be different and you should be doing different things , your actions should impact the society .The various things i could think of are:-

1)Become a Teacher:You should do a Phd and by educating the people you are actually making a difference to the society,you will also gain respect by doing so.

2)Set up your own enterprise:You can set up your own enterprise,by doing this you can provide employment and you can take things to next level,believe me you dont need huge sum of money for some of the enterprise.

3)Drive innovation:Go into research, develop something innovative .Innovation drives the world and you can achieve money and fame.

4)Become a public servant:you can do so by joining civil services or joining a non profit organization,again its a chance to do something good and meaningful but it should not be to earn money.

Note:you can earn money by becoming a investment banker or management consultant but i dont think in any way your life will become large.
