Raising seed round?

Hey everyone,

I have started raising a seed round for my startup lazyapply.com and being a first-time founder who is raising money, I have a lot of doubts and want to make sure I make fewer mistakes so

Requesting experienced fellow founders to drop some advice on -

1. How to find an investor? ( Any list available)
2. How to approach investors on LinkedIn?
3. Something that you knew when you started first?

I am pretty sure that it will help a lot of other founders here as well. Requesting fellow founders to upvote so this post can get enough responses so we all can learn together.
