It should come as no surprise to anyone who is familiar with St. Teresa of Avila that her vision of the Cross is completely interpenetrated with love; not the Love of God for humanity, which she acknowledges and exalts, but the love of the person for Christ and His Cross. This is an interesting perspective and one that may help shed some light on the question of "taking up our crosses."
The Way of the Cross with the Carmelite Saints St. Teresa of Avila
They are too attached to their honor. . . . These souls, for the most part, grieve over anything said against them. They do not embrace the cross but drag it along, and so it hurts and wearies them and breaks them to pieces. However, if the cross is loved, it is easy to bear, this is certain.
For St. Teresa of Avila, love is the measure of all things. Everything that a person does is measured by the love lavished on it. When someone loves to do carpentry, the shelves, cabinets, and woodwork of his (or her) house shows the attention given to detail. When a person loves to cook, the meals prepared show the investment of time and love.
Most people's embrace of the cross is summed up in the word endurance. The cross is not to be loved, or even to be examined, and only just barely is it to be borne, and then, often, only with ill grace. What the Saint says here is that whatever makes up the cross for a person needs not merely be borne and dragged along--in this there is mere destruction. But it must be loved, loved as the present it is from the God who gives it. While wearing braces, a person does not love them, but afterwards, for years of straight teeth and good service, the love of them grows. Leg braces are nothing great to wear, causing the owner pain and humiliation, but without them there is no motion of one's own.
The cross is a gift from God. The crosses a person is called upon to bear are to right the irregularities in that person's spirit, to repair the flaws of original sin, and to make that person a perfect vessel of grace. It's hard to love what hurts, but when what hurts leads to perfection, a person can do it. It often hurts to lift weights, to jog, or to engage in other such activities--but because of the benefits that accrue to these activities many people do them, and many people "love" them. If so for things that help make better the life of this world, then how much more so for things that help make better life now and in the world beyond?
