What tense you are in reflects what state you are in...

The Vietnamese Buddhist monk and philosopher, Thich Nhat Hanh,
writes about enjoying a good cup of tea. You must be
completely awake in the present to enjoy the tea. Only in
the awareness of the present can your hands feel the
pleasant warmth of the cup. Only in the present can you
savor the aroma, taste the sweetness, appreciate the
delicacy. If you are ruminating about the past or
worrying about the future, you will completely miss the
experience of enjoying the cup of tea. You will look down
at the cup, and the tea will be gone.

Life is like that. If you are not fully present, you will
look around and it will be gone. You will have missed the
feel, the aroma, the delicacy and beauty of life. It will
seem to be speeding past you.

The past is finished. Learn from it and let it go. The
future is not even here yet. Plan for it, but do not waste
your time worrying about it. Worrying is worthless. When
you stop ruminating about what has already happened, when
you stop worrying about what might never happen, then you
will be in the present moment. Then you will begin to
experience joy in life.

And that's the reason why I love using this tense.
