Being present means your mind shows up to the same place your shoes did.

Turning up physically is the part everybody manages. The harder half is arriving mentally, and it is entirely possible to spend a whole evening in a room while thinking about a conversation from earlier or something happening on Thursday. Your body is a reliable attendee, and your attention has to be walked in separately.

Check where your mind actually is a few times today. When you find it somewhere else, bring it back without making it a failure, since it will wander again in about a minute and that is normal. Being present is not a state you achieve. It is a short return trip you make over and over.
