It's because I wasent several months without a computer when my PC got broken.

But I had my smartphone, andso I guess ithat's the same.

If it would behappened now, or next week for example, I believe it wouldn't be a problem for me.

For a start, I would do all little things I planned to do, but had always put off.

And of course, not being distracted by gadgets means I could spend more time to looking into myself, meditatateing and reflecting to see where my thoughts go.

It would be also a pleasure to read a fascinating book, -- to dive into its dimensionworld for a couple of days aslike I did when I was a teenager.

It's because I wasspent several months without a computer when my PC got broken.

"I was several months without" is technically correct (cf. "was without child," etc.) but sounds quaint in informal, non-literary writing.

But I had my smartphone, and I guess it's the same [thing].

I did everything on it, but to be honest, I prefer using a computer rather than using a smartphone.

If it would beere right now, or next week, for example, I believe it wouldn't be a problem for me.

I would also replace "it" for clarity, but I think it's fine.

For a start, I would do all little the things I've planned to do, but always put off.

"I planned": I planned in the past
"I have planned": I plan to now and in the past

And of course, not being distracted by gadgets means I could spend more time to look into myself, meditatate and reflect to see where my thoughts go.

Alternatives to "look into myself":
- introspect
- look inwards

It would be also a pleasure to read a fascinating book, to dive into its dimension for a couple of days as I didwould do when I was a teenager.

I think the average native speaker would think "as I did" is fine, but this sounds more appropriate to me. I am having trouble locating an explanation though. "Used to" could also work.
