It states in Pirkei Avos (4:1): “Who is wealthy? He who is happy with his portion.” 

The Sfas Emes zt’l notes that this also refers to your portion of ruchniyos. Even for ruchniyos, one should focus on the half-full cup. 

You indeed wanted to learn more Gemara, to daven with more kavanah, etc., but think about what you already did accomplish and rejoice with it!
