In my opinion... According to me....

There are plenty, but here are the ones I can think of: - I believe that... - In my opinion... - I reckon that... -Personally... -I have to admit that (I would use this for a negative thing, e.g., "I have to admit that I'm lazy.") - In my experience... - It seems to me that... - I am convinced that... -I am of the opinion that...( this one is quite formal) - In my eyes...(this is a figure of speech. e.g. "In my eyes, television is not as good as it used to be.") - As far as I'm concerned... -I tend to think that... -I would say that... -In my view... - I would argue that...(I would use this if someone says something you disagree with)

Say this, if you want some discussion on the topic: "I am wondering about ..........." "In my opinion, I think it's a good idea to...(invest in Coca Cola stocks), (open up a bank account), (pay my bills with a credit card, and put it on automatic pay) (move to a larger apartment and share it with someone), etc. What do you think about that?" "I am considering doing this.....(moving closer to work), what is your opinion about that?" "Do you have any ideas about the best way to get a better position at my company? I'm wondering how to go about that" "Do you think it would be wise to .......?"

" i think...", " I guess...", " I believe...", " for me,...( more colloquial) " all are good choices to express ur thoughts. ;)
