Hello community!

I'm quite new to the investments world, but I've studied a bit and I'd like to have an additional opinion about how to invest my money.

I have 20k euros to invest, and I plan to add 400 euros every month.

I plan to let this money grow for at least 20 years or even more.

I have decided to invest in I decided to invest in an All-World ETF and my choice fell on $VWCE (+1.33%) (I have also considered the $FWRG (+1.36%) which has lower TER, but also lower fund volume and higher spread).

But I'd like to add one or more (not to much) ETFs to boost up a little bit the performance and I was thinking about some ETFs on the Nasdaq100 or the S&P 500 indexes (like $SPYL (+1.27%)
$SPXD (+1.01%)
$VUAG (+0.99%)
$VUSA (+1%)
$EQQQ (+1.73%)
$UST (+1.96%) ).

What do you think about this idea? I have read that there is an overlap problem doing this but I'd like to have more opinions about it.

I think also that would be nice to have some money coming from dividends for everyday use, but I haven't searched nothing and it's not essential for me.

Have you got any suggestions?

Thank you in advance
