know thy stuff well, read and experiment a bit with smaller sums, add regularly, don't panic

I would say build up your savings and capital first.

By building up your savings, you would have built up good spending and saving habits. This will carry you a long way in future. If one is unable to save well, then investing is not going to help much in building wealth.

Along the way, you can learn more about investing through books, free courses and videos, online blogs.

U can try doing Regulare Savings on DBS bank for the STI ETF

as it gives flexibility, u can stop, hold, take out anytime u want

that could be a good way to start!

If you are in poly, I believe you have time on your side i.e. you are young. Time is the most important resource that you can have.

Since you are asking about investing, I am assuming that you also are aware of the importance of savings and protection. Do a 360 review if you have not thought about them. This reply will focus on the investing portion and taking a very long term view.

Invest as much as you can, as early as you can. Then let time do its magic. Compound interest works on the same principle.

You can choose to go with a low cost monthly investment plan into ETFs or robo-advisers with a portion of your planned investment amount. The other portion can go to SSBs.

Learn along the way but get started first.
