Like LASER focused on what you want to specialize in.

You will likely need a good laser printer or use a company like Vistaprint to make them though.  

I saw so many things around me which could have been done better thus, I decided to be an entrepreneur.I then partnered with a European company that provides laser and IPL equipments.

It is going to take laser focus, but it is amazing what one can accomplish in an hour or two a day if you know what to do.  

Direct mail is very powerful, but far from what I would call laser focused.

I have no problem with that, but I hardly have any money for myself, all the while my ex-wife is getting tattoos, buying expensive clothes and spending it on unnecessary things.I want to get the financial freedom to not have to worry about the little things.

They might even be tattoo artists while off the property, that doesn't mean they will turn your unit into a tattoo parlor. 

My advice for new investors is to stay laser focused on developing a strong track record.

If someone is a member of a protected class and you don't like their tattoos, or hair, or behavior then you can still reject them on the basis of the factor you don't like.

It is easy to just say that someone else in the long line of potential tenants got it first, they don't know each applicant's timeline.You do owe it to yourself to be choosy....what if someone passes your background checks but has gang tattoos?
