What is another way to say "in my opinion"? [closed]

What phrase should I use to prevent the redundancy of saying "In my opinion..."?

Oftentimes, I always say this phrase whenever my teacher asks for my opinion about certain subject or topic and it sounds a little redundant and annoying.
Is there any alternative to say the above-mentioned phrase? -- Alternative, in a way, that it will sound witty.

• As I see it

• it seems to me

• It seems likely

• I have observed

• One can postulate

• In my experience

• As far as I can tell

• Consider this:

• You can see that

• One might argue that

• the evidence can lead one to conclude

"I think" is a strong yet simple start as noted in the initial comment.

But another technique is first repeating back the subject in such a way you demonstrate a thorough understanding of the question. And the subject.

In the fields of debating and rhetoric lots of inspiration can be found.

Have fun!

To my mind, "to my mind" can work in lieu of "in my opinion".

Futhermore, and from my standpoint/perspective, "from my standpoint/perspective" can also work in lieu of "in my opinion"...

And since I cannot comment on Nickys answer, I'll add here:

"By my reckoning"

"I reckon"? I use that a lot. Also sounds pretty sophisticated ;)
