For a long time practical philosophy was considered the doctrine of the good life and of happiness. Morality was often considered a part of this or also a means to reach happiness. Kant's accomplishment lies in having strictly distinguished both. The proper or pure practical philosophy only deals with moral duty in his system, unconcerned with our personal adventage or happiness. Nevertheless Kant also in many places made remarks about what a good life consists of. And the cliché of Kant only preaching and himself living cold, joyless dutifulness is not true: Sensuality and our desires according to him should be governed by reason, but not supressed, rather they should get their due.

The relationship of reason and sensuality, moral duty and prudent joy of life and his rejection of grumpy ethics and the virtue of monks Kant discusses most extensively in his lectures on moral philosophy: https://www.archive.org/details/kantsgesammeltes271imma | https://archive.org/details/kantsgesammeltes272imma | https://archive.org/details/kantsgesammeltes0027kant_s1s1/mode/2up (I am not aware of any free English translation).
