The Furture and bBig dDecisions

Just "future" is okay, but "the future" is more natural.

My family say I'm indecisive, I usuallybut I disagree because lotsmost of times those things just aren'he decisions aren't that important so I just let them decide for me.

"the decisions" should be stated first, and then you can use less specific language ("those things") to refer back to it.

Using "just" 2 times is grammatically okay, but I replaced one with "that" for style reasons. Not using the same word twice in one sentence sounds more polished.

Note: "my family say" is correct in British English, but not American English. In American English, "my family says" is correct.

But recently I had to make an important decision that is likely to have a huge impact ion my life.

In the beginning, I couldn't understand how they could not be interested oin it, but now I actually find it better that they didn't do anything.

Using connectors like "but" or "and" is necessary when you have multiple ideas in a sentence.

I was feeling lost and anxious, but I calmed down and began to figure out what is bestter for me.

"better" is possible, but "best" is more natural.

I don't know if it was a good decision because it will just come trueonly become reality in February, but I'm happy with it.

We say wishes and dreams come true, but it doesn't work for decisions.

We say decisions are realized, come into effect, become reality, and so on.
