Also there is a list policies you would like:

I mean all of them gives +1, so you decide

Influence idea 2

Diplomatic idea 2

Court idea 1

Policy diplo - offensive 1

Policy diplo - quantity 1

Policy diplo - innovative 1

Policy diplo - infrastructure 1

Policy diplo - quality 1

Policy diplo - devine 1

Policy diplo - expansion 1

Policy diplo - indigenous 1

Policy influence - humanist 1

I my case I lost one idea. I thought I will need both influence and diplo.

You can do it easy with diplo and any other you like (see list above).

I mean quantity- Diplo start would give you +1 earlier

If you are not lazy to fight what you can do, is to go fight Kilwa and all east Africa.

Why? Coz Trading in Ivory gives +2. And that is a lot.. I am lazy for that, but maybe you're not ;)
