@Hinemarangai,
Those verbs are in the first person singular indicative.
They translate as "I think", "I draw", "I create".
You have to think about what you want to say.
Do you want to give commands? If so, you will need the imperative.
Do you want these verbs to function a nouns? If so you will need the
infinitive (as in "to think", "to draw", "to create").
The word you are using for draw is used in the sense of pulling or attracting.
Is that what you mean or do mean it in the sense of sketching?
