There are many possibilities with slightly different meanings. What do you really want to say?
EDIT:
If the mistakes cannot be listed as nouns, you might be able to use relatively brief participial phrases in the confines of a single sentence.
I do not want to repeat my past mistakes of underplaying economic disruption and over-emphasizing technical hurdles.
This approach works if the mistakes can be expressed in short phrases. Otherwise, you can use multiple sentences.
I shall not repeat my mistake of stressing the benefits that such a technology provides to the general public in the long term while underplaying the economic costs that new technologies frequently impose on unskilled labor in both the short and long term. Nor shall I err again in over-estimating the delays that purely technical hurdles may impose on adoption of a new technology.
