Check out the page I've made for my portfolio here. Like I also mention there a portfolio should always be a work in progress and so is this one.
I have waited for a long time, trying to figure out how I wanted it to look like, getting the right things and all the time I've felt like it wasn't good enough.
But not so long ago I realized that I shouldn't be satisfied. That that is not the point of a portfolio. Or anything for that matter. You can never get somewhere if you don't take the walk. You never get better if you don't practice. Being scared, intimidated or expecting yourself to be perfect will only stand in your way. So now it's out there. I am still not very happy with it, but it still feels nice. And I'll keep working on it and make it better and better and better and keep updating it again and again.
I hope this inspires you to also do whatever you dream of, take the first step, practice. And realize that you will only get to where you dream of by taking each step on the journey.
