So we'll I know alot of people would vote for having a mentor but read this first.
So my theory is that, when you want a mentor you're probably looking for someone above you right??
And a partner will have to be someone in your level or a bit higher or lower.
So which is better ? I will say partner because when you have a mentor he is going to train and teach you how things worked in his time, when he was starting out...
And we all know strategies change, algorithms waver and fluctuate, so their advice might not be the best for a start up.
But a partner is someone that is in the same field and sometimes in the same level and who is also working hard and smart like you, and figuring out new strategies to benefit the both of you, while you do the same.
So you two will figure things out that currently works for startups.
(This doesn't mean a mentor is completely ruled out but their opinions and help will also be helpful after you conduct research on them 😉😀😄)
