MY future in Marketing

I feel confident in the direction that my career is going.
I know it's still early days for me and the marketing, But things are going well.

I think that as long as I continue to build my portfolio, More opportunities will continue to come my way.

With that being said- there is still alot of things that i need to learn.

I only have the most tenuous grasp of graphic design, for example. I dont know how to use adobe illustrator at all, although i can use adobe photoshop somewhat.
Honestly, for most design projects for my clients, I use gimp or fotor.

And that's a serious problem.
In addition, I can't video edit.

But wait, there's more!

I know S.e.o. tactics, and I know about backlinks, listings, etc.

I can run a social media campaign, and i'm aware of metrics, and even the more complex analytics programs such as sem rush.

But I am missing something very important in facebook business.
so important and i dont even know how to set it up.

I think i should still take an s.e.o. class, as well as graphic design and video editing class.
and although i took a social media marketing class, I should take a social media business marketing specific class.

Ugh. It makes me feel discouraged.
Now, I can do whatever my current clients need me to do. I can even design nice looking ads, boosts, digital flyers, etc.

But I deeply feel the void in my knowledge.

This must be remedied.
