I'm very strong on the thinking end of the spectrum, but that doesn't mean I don't have powerful emotional sides.
You see, making ideas and actions based on rationality or logic can perfectly coexist with strong sentiments. Sometimes we can even do things by way of the emotions, but it's generally in the service of a reasoned cause.
For reference, I'm a deep humanitarian, and I truly believe it would be ideal for us to share our happiness with the world, but I wish for this because it's a much better context for advancing the progress of objectives, such as the evolution of civilization and bringing enlightenment to the mind. Truly this leads to expansion in the most integrative way.
Feelings can help give focus to our reasonings as well, make us act with better values and use knowledge with virtue.
To answer your question, find something the "thinker" has discovered or developed of mental importance to himself, and then let the enthusiasm for this point of interest spread amongst yourselves, eventually even out into the world if it's open to that. Really explore how the rationality can give hopes for the free explosion of happiness.
Ultimately, if we thinkers want something, no matter how rationalistic it may be in nature, it's because it flows from the well of happiness at the heart of our beings.
