After my corrections/suggestions:

All of we yogis or aspiring yogis started at the same point once in our lives. We find this beautiful practice at different ages and moments of our lives. We find it when it was meant to be, when we needed a change or needed more self-awareness. If you're still having doubts about this world full of positive thoughts and kindness and you're feeling too shy to attend a yoga class or workshop, or if you've never done yoga on your own, you should probably check this article out.

So, here it comes the question: "How should I start"? The answer is obvious: start from the beginning. Follow these seven simple steps, and remember, feel free to modify whatever makes you feel uncomfortable.

1. Choose your special space to practice. I strongly recommend to choose your backyard or any outdoor place you're allowed to be in. Don't go into your neighbor's beautiful yard, even if the idea of doing yoga surrounded by colorful flowers and fresh air is a temptation, you might be accused of breaking into his property (I'm kidding yogi fellows). If you don't have such special place to practice, you’re always able to use the back room. Don't focus on the place, focus on your practice. I've practiced in my TV room for 6 months and I'm here I've survived and guess what? You will, too.
2. Get your mat, blocks, toilet, bottle of water, straps and everything you need to make your practice as comfortable and as fun as possible. Blocks and straps are super helpful when you're having troubles with some arm balances, jumping through, handstands and other poses. There's almost one hundred possible ways to use these tools. Try it out!
3. Start with the basics. A few sun salutations are the best way to begin your practice. If you're a lover of inversions and advanced postures, remember warming up your body before putting your world upside-down. The most important about being a self-taught yogi is that you have to be aware of your body's needs.

"When we were missing a change or to be more aware about ourselves."

In English, this sentence is kind of confusing. With the word "when" at the front of it, it sounds like a partial sentence. I changed it above to what I think you were trying to say.

"on your own" instead of "by your own"

Just an English saying, I suppose.

"Start with the basics." instead of "Start from the basics."

Both ways are grammatically correct. We "start from scratch" or "start from square one" (there are a million of these, I'm sure), but when it comes to the "basics", we always start "with" them instead of "from" them. I don't know why...

Your English is excellent. I would have assumed that a native speaker wrote this.
