Do you think having a blog and being consistent on it have nowadays some worth?

If you're in it for the money, then no. Nobody reads blogs anymore.

It’s worth it if you do worthwhile things and aren’t going into a career that requires ‘blank canvas’ professionalism. Every now and then I get tempted, but in my profession you don’t want clients googling stuff about you.

You have to see how can you make it profitable. If it is written the way as to drive business to you. I remember when I used to freelance and started answering technical questions on Quora, after a time I started to get business queries on my Quora account.

It's worth it. But insta is important to attract the audience for the blog

I have a blog I love, that I write an entry for every day, it’s very fulfilling for me and I feel better when I create an entry for it. It’s really just for me and not for profit. I do get likes and visits. I have just made it private yesterday tho. I think it’s worthwhile if it makes you happy. But it would be very hard to profit off. People who want profit from blogs/newsletter/their writing use substack.

It depends what you want out of the blog. If it's a just a place for you to collect your own things and you like the format, then go for it.

If you want people to look at it and for it to gain a lot of followers, you'll probably have to do a lot more advertising outside of the site in order for it to become successful.
