That's where I think the small gestures come in handy.
I was chatting to my mother-in-law the other day and I mentioned how I like to try to live by the maxim "The smallest gesture is better than the grandest intention" - and it's true. So often we'll think about all the things we 'should' do that'll make a difference, but because we're so busy and life gets in the way we just don't get around to it. Then we feel guilty and often the friend we hoped to make feel better just feels neglected.
Instead of coming up with a beautifully made card to send to someone - it's best to send off a quick email or text to say, "Hi, thanks!" or "Thinking of you x". Obviously a phone call's better - but a fill in text can be like a smile, just to let them know they're in your mind.
What small gesture can you make today?
